2. DESCRIPTION
The Powersine Combi is an all-in-one combination of a DC to AC true sinewave inverter, an
advanced multi-stage battery charger and a high speed AC transfer switch. All this is build
into one compact, yet installer friendly enclosure. Besides these three main functions, there
are several unique features offered as well. Some of which benefit from the strong
interaction between the three main functions.
The main task of the Powersine Combi is to act as an uninterruptable AC power supply (UPS).
In case of a grid/generator failure or disconnection, the Powersine Combi immediately stops
charging the battery, releases the AC transfer switch and activates the inverter which takes
over the supply to the connected loads. All this is achieved so fast, that even very critical
loads like computers will continue to operate without any problems. In case the
grid/generator is reconnected again and the voltage and frequency are within acceptable
limits, the Powersine Combi activates the AC transfer switch and battery charger again, while
deactivating the inverter. The connected loads are now supplied again by the grid/generator
without any interruption.
Additionally, the Powersine Combi offers features like :
- AC Input Power Boost, which temporarily assists weak AC input sources when the
connected load needs more power than available from the grid or generator.
- AC Input Current Limit, which limits the maximum current consumed from the AC
input source by the Powersine Combi. This limit is user adjustable.
- Power Factor Corrected AC Input, which optimizes energy efficiency and makes sure
that the maximum amount of charging current is available from your AC source.
- Intelligent 4-stage charge programs, user programmable to fit any battery type.
- Fully programmable inverter, transfer switch and battery charger parameters, using
the SAMLEX Dashboard for Windows software.
- Programmable alarm relay, for optimal control of external devices like generator
starting or selective load disconnection.
- Freely assignable trigger input, which allows the user to control the Powersine Combi
by external events.
- Temperature controlled fans, to guarantee silent operation under less than full load
conditions.
- Temperature compensated battery charging, using the standard supplied battery
temperature sensor for maximum battery lifetimes.

3. CONFIGURING THE POWERSINE COMBI
3.1 General
The Powersine Combi can be configured in two ways. Using the DIP switches located in the
connection bay, a small selection of basic settings can be made. In most cases this will be
sufficient to quickly setup the unit for typical applications. Another option is to setup the
Powersine Combi using the SAMLEX Dashboard for Windows software. This software is
included in the optional SAMLEXLink to USB Communication Kit (art.# 64660), which also
contains an isolated interface box required to connect the Powersine Combi to a PC. Using
SAMLEX Dashboard, all available parameters can be edited, and it is also possible to edit or
create your own battery charge programs.
!
CAUTION
When configuring the Powersine Combi by SAMLEX Dashboard, make sure that DIP switch 1
is set to ON (External). When set to ON, all remaining DIP switch settings (2 up to 7 or 9) are
ignored and the Powersine Combi will always load the parameter settings as configured in
SAMLEX Dashboard.
When DIP switch 1 is set to OFF (Local) again, DIP switch 2 up to 7 or 9 are overriding the
corresponding parameter settings previously made in SAMLEX Dashboard. The parameters
that cannot be configured by DIP switches, shall return to the factory default settings.
This manual will only describe the DIP switch settings and all relevant factory default
parameters. Configuration by SAMLEX Dashboard will be explained in the SAMLEX
Dashboard manual that comes with the SAMLEXLink to USB Communication Kit.
3.2 Factory default parameter settings
The table below shows an overview of the most relevant factory parameter settings, as
stored in the Powersine Combi. These settings are based on an average application. SAMLEX
cannot guarantee that these are correct for your specific application. Please check all
parameters carefully, especially the battery charging voltages.
Parameter
Inverter frequency
Value
50Hz
Description
Output frequency in inverter mode. Can be set to 50Hz or 60Hz
Configurable by
DIP switch (DIP 2) and Dashboard
Parameter
Inverter voltage
Value
230V
Description
Output voltage in inverter mode. Can be set from 200V to 240V
Configurable by
Dashboard

Powersine Combi
7
Parameter
Low Battery Protect
Value
On
Description
Enables or disables low battery protection with user programmable
shutdown, restart and delay values (standard respectively 10V, 12V and
5 seconds). Turning Low Battery Protect off, results in immediate inverter
shutdown when the battery voltage is less than 8.0V.
Configurable by
DIP switch (DIP 3) and Dashboard
Parameter
Automatic Stand By (ASB)
Value
Off
Description
Enables or disables ASB. If enabled, the inverter will jump to ASB mode
automatically, when the connected load power consumption drops
below a user programmable level. In ASB mode the inverter pulses it’s
output sinewave in order to detect when the connected load requires
more power again. While running in ASB mode, the Powersine Combi
itself draws significantly less current from the battery. As soon as the
load power demand increases again, the inverter will automatically jump
to continuous mode delivering uninterrupted power to the load. When
disabled, the inverter will always run in continuous mode, which is better
for critical loads like computers, clocks and AV equipment.
Configurable by
DIP switch (DIP 4) and Dashboard
Parameter
AC input voltage range (transfer switch)
Value
180V –270V
Description
Input voltage range which is accepted by the Powersine Combi for
feeding through to the connected load. Two AC undervoltage values can
be set. An absolute undervoltage level which directly releases the AC
transfer switch when exceeded (factory setting = 150V), and a delayed
undervoltage level, which releases the AC transfer switch after a certain
delay (factory settings are 180V and 5 seconds). The charger stops
charging when the AC input voltage drops below 185V and restarts again
above 190V.
Configurable by
Dashboard
Parameter
AC input frequency range
Value
45Hz –65Hz
Description
Input frequency range which is accepted by the Powersine Combi. Can be
set to full range (45Hz –65Hz), or to a smaller range within the 45Hz
lower and 65Hz upper boundaries.
Configurable by
Dashboard
Parameter
AC Input Current Limit
Value
16.0A or 30.0A (depending on model)
Description
Represents the maximum continuous current that the Powersine Combi
will draw from the AC input source. To assure this, the Powersine Combi
will either reduce the charge current automatically, or (when enabled)
will activate the AC Input Power Boost feature which will supply the
additional power demand by running the inverter in parallel with the AC
input source. When the connected load still draws too much current, the

Powersine Combi
8
installer can either choose to deacvate the AC transfer switch, or keep it
closed and allow it to exceed the AC input current limit value. This value
can be set from 1.0A to 16.0A or 2.0A to 30.0A (depending on model) by
Dashboard or the oponal Universal Remote Control.
Configurable by
Dashboard and Universal Remote Control
Parameter
AC Input Power Boost
Value
On
Descripon
AC Input Power Boost temporarily assists weak AC input sources when
the connected load needs more power than available from the grid or
generator. This is accomplished by running the inverter in parallel with
the AC input source. The inverter can add power up to it’s nominal
output power rang assuming the baery is healthy. This parameter can
be set On or Off.
Configurable by
DIP switch (DIP 7) and Dashboard
Parameter
Ground switch
Value
Enabled
Descripon
The ground switch is an internal relay that automacally connects AC
output Neutral (N) to Protecve Earth (PE = chassis) in inverter mode.
This enables the use of a ground fault circuit interrupter (GFCI) at the AC
output of the Powersine Combi. When a non-grounded (floang-) output
is required, this Parameter can be disabled.
Configurable by
DIP switch 8 (on PSC2000-3500 models only) and Dashboard
Parameter
AC input fail sensivity
Value
Normal
Descripon
This parameter can be set to Very Low, Low, Normal, High and Very High.
The value of this Parameter decides how fast the Powersine Combi
detects a signal fail at the AC input. The lower sengs are resulng in a
slower AC input source →inverter transfer me, while the higher
sengs result in the fastest transfer mes. The sengs Low and Very
Low can be used when the AC input signal is distorted or unstable, which
could be the case when a small generator is used. The sengs High and
Very High can be used when the Powersine Combi is connected to a solid
grid or quality generator. The factory seng Normal is a good
compromise, which sll results in a fast AC input source →inverter
transfer me of less than 5ms, while being reasonably immune against
distorted AC input signals.
Configurable by
Dashboard
Parameter
Baery type / Charge program
Value
AGM
Descripon
The default charge program AGM is compable with typical AGM type
baeries, but can be used for other types of lead-acid baeries as well.
Please make sure that you always check if the Powersine Combi charge
program sengs, are compable with the used baery! The AGM charge
program absorpon voltage is 14.3V (28.6V@24V) and the float voltage
is 13.3V (26.6V@24V). Other selectable charge programs are Flooded, GEL
and Lithium/Custom. For further charge program informaon, please see

Powersine Combi

chapters 3.3 and 5.1.
Configurable by
DIP switch (DIP 5 and 6) and Dashboard
Parameter
Charge current limit
Value
100%
Description
This parameter sets the maximum charge current in percent. This value
can be set from 10% to 100% by Dashboard or the optional Universal
Remote Control. You can set this parameter to a lower value when the
connected battery is too small and cannot handle the maximum charge
current, or when you wish to (temporarily) reduce the charger current
share, in the total amount of current flowing through the AC input of the
Powersine Combi.
Configurable by
Dashboard and Universal Remote Control
3.3 DIP switch settings overview

!
CAUTION
1) Invalid baery type sengs can cause serious damage to your baeries and/or connected
baery loads. Always consult your baery's documentaon for the correct charge voltage
sengs.
2) When charging and discharging lithium baeries with built-in BMS, please make sure to
correctly size the baeries. Due to the larger Depth of Discharge capabilies of lithium
baeries, it is common to install lithium baeries with a smaller capacity compared lead
based types. It is however important to carefully check if these baeries can sll accept
the maximum charge current of the Powersine Combi without tripping its internal BMS
relay. The same applies to the baery's capability to deliver the peak discharge currents
that the Powersine Combi needs to power demanding AC loads. An excessively tripping
BMS relay may over me cause damage to the Powersine Combi.

4. GENERAL OPERATION
4.1 Operating the Powersine Combi
The main switch on the Powersine Combi has three positions : On, Off and Charger only (see
image in chapter 4.2).
When switched to On, the Powersine Combi will perform all tasks automatically. It will
power up in inverter mode, supplying power to the connected load. When a grid or
generator is connected to the AC input, the Powersine Combi will analyse this signal. If the
voltage and frequency of this signal are both within the required limits, the Powersine Combi
will synchronize to the input signal and activates the AC transfer switch automatically. Now
the connected loads are being powered from the AC input source and the Powersine Combi
will also start charging the battery. As soon as the voltage or the frequency of the AC input
signal are exceeding the required limits (for example when the AC input signal disappears),
the Powersine Combi will immediately stop charging, release the AC transfer switch and
activate the inverter again. All this happens so fast, that the connected load will not be
disturbed.
When switched to Off, the Powersine Combi is completely shut down and cannot be
activated by a remote switch or the Universal Remote Control either. In this mode, the
Powersine Combi will draw no current from the battery.
When switched to Charger only, the Powersine Combi will disable the inverter mode and will
only work as a stand alone battery charger. As soon as a usable AC input signal is available,
the Powersine Combi will activate the AC transfer switch and starts charging the battery.
When the AC input signal fails, the AC transfer switch will be released again and the charger
stops charging. No AC signal will be present at the Powersine Combi output when there is no
AC input signal either.
Information about the LED indicators on the frontpanel and the different error mode codes,
can be found in the next chapter.
4.2 Powersine Combi LED indicators and error modes
Please see the next image for an overview of all LED indicators on the Powersine Combi
frontpanel, as well as the location of the main switch.

Powersine Combi
13
The frontpanel can be divided into four sections :
1. Dual function level bar. Indicates the percentage of delivered output power in inverter
mode (turns red if more than nominal output power is being delivered to the load). In
charger mode, this level bar indicates the percentage of delivered charging current.
2. Mode indicators. Indicate the operating mode of the Powersine Combi, as well as the
status of each different mode (see explanation below) :
‘charger on’ LED
Off : not charging
On (green) : charging
On (blinking red) : error (see chapter 4.2.1)
On (red) : charger disabled
‘inverter on’ LED
Off : not inverting
On (green) : inverting or power boosting
On (blinking red) : error (see chapter 4.2.1)
On (red) : inverter disabled
‘AC in’ LED
Off : No AC input present, transfer switch open
On (blinking green) : AC input present and within range, Powersine
Combi is synchronizing
On (green) : AC input approved, transfer switch closed
On (blinking red) : AC input present but out of range
On (red) : AC transfer switch disabled

Powersine Combi

3. Charge status bar. Gives a rough indication of the charging progress, see below :
LED 3a : 100% full (ready)
LED 3b : 80% full
LED 3c : 50% full
LED 3d : empty
4. Power on, off, charger only switch. See chapter 4.1 for more explanations.
4.2.1. Error indications
When the so called mode indicator LEDs are blinking red, an error has been detected. Each
mode indicator LED can either blink red individually, or combined along with one or more
other mode indicator LEDs. There are five different error indications, each with their own
blinking pattern :
One flash in a row : Battery related error (too low or too high battery voltage, too
low or too high battery temperature, too high battery ripple
voltage, battery defect)
Two flashes in a row : AC overload error (AC load requires too much power from the
inverter, AC output short circuit)
Three flashes in a row : High temperature error (Powersine Combi shuts down on high
temperature)
Four flashes in a row : Device error (an error has occurred inside the Powersine
Combi. Please return for service)
Five flashes in a row : Charge program error (only for ‘charger on’ indicator LED).
Charge program selection set to Custom, while custom made
charge program contains an error or time-out.
The Powersine Combi will mostly recover from an error mode automatically when the cause
of the error has been resolved. However, when an error has occurred due to a high battery
ripple voltage or an AC transfer switch overcurrent, the Powersine Combi needs to be
switched off and on again manually (manual restart). The Powersine Combi also needs to be
restarted manually, when too many battery or overload errors have occurred within a short
period of time.
4.3 Programmable Alarm relay
The Powersine Combi is equipped with one or two (depending on model) programmable
potential free alarm relays. Standard, this relay (or relay 1 on PSC2000-3500 models) will be
activated when the unit shuts down and jumps to an error mode. The alarm relay de-
activates again when the error has been resolved and the Powersine Combi is running in
normal operating mode again.

Powersine Combi
15
Relay 2 on the PSC2000-3500 models will be activated only after the AC supply has become
available. In case of battery operation, Relay 2 will deactivate immediately. This can be used
to switch less critical AC loads (i.e. electric boiler, aircon) on and off that are allowed to be
supplied by the mains or generator only.
Using SAMLEX Dashboard, it is also possible to configure the programmable relays to
perform a different task, like starting a generator when the battery voltage has reached a
certain low voltage level.
Both normally closed and normally open contacts of these relays are available. For the
PSC1600-1800 models, the maximum relay contact ratings are 30Vdc/1A or 60Vdc/0.3A. For
the PSC2000-3500 models, the maximum relay contact ratings are 30Vdc/16A or
250Vac/16A.
4.4 Trigger input
The trigger input offers a way of externally controlling the behaviour of the Powersine
Combi. The trigger input can be connected to an external switch or a potential free relay
contact. By closing this external switch or contact, a user programmable ‘action’ will be
performed. Such an action could for example be to release the AC transfer switch,
temporarily disable the AC input Power Boost feature or force the Powersine Combi to
switch to inverter mode. All this can be configured in SAMLEX Dashboard. The PSC1600-1800
models are equipped with one trigger input, while the PSC2000-3500 models are equipped
with two trigger inputs.
4.5 Load requirements in inverter mode
Before you connect your appliance(s) to the Powersine Combi AC output, always check it's
maximum power consumption. Do not connect appliances to the AC output requiring more
than the nominal power rating of the inverter continuously. Unless these appliances are
switched on only when the AC transfer switch is activated, and power is drawn from an
external source with a larger capacity than the inverter.
Some appliances like motors or pumps, draw large inrush currents at startup. It is possible
that the startup current exceeds the overcurrent trip level of the inverter. In this case the
output voltage will shortly decrease to limit the output current of the inverter. If the
overcurrent trip level is continuously exceeded, the inverter will shut down and
automatically restart within 20 seconds. In this case it is advisable to disconnect this
appliance from the inverter, since it requires too much power to be driven by this unit. The
Powersine Combi needs to be restarted manually when it has shut down due to overloads
for four times in a row. Note that at higher ambient temperature levels, the overload
capacity of the Powersine Combi will be reduced.

5. CHARGER OPERATION
5.1 Charge programs
All standard selectable charge programs (using DIP switches 5 and 6), perform a four stage
IUoUoP charging process comprising of a “Bulk”, an “Absorption”, a “Float” and a “Pulse”
stage. The image below visualizes the four stage charging process :
In the Bulk stage, the charger delivers full output current and typically returns approximately
80% of charge back into the battery once the absorption voltage is reached. During this
stage, the battery empty and battery 50% full indicators will be lit depending on the Bulk
charge progress. When the absorption voltage has been reached, the Absorption stage will
be entered and the battery 80% full indicator will be lit. This stage will return the final 20% of
charge to the battery. The output voltage is kept at a constant level and the charge current
decreases as a function of the battery's state of charge. When the charge current has
dropped below a certain value or when the maximum absorption timer has been expired,
the Float stage will be entered. The battery full Indicator will be lit and an acoustical
message will sound, indicating that the battery is full. In this stage the battery voltage will be
held constant at a safe level for the battery. It will maintain the battery in optimal condition
for as long as the battery remains connected to the activated charger. Connected battery
loads will be directly powered by the charger up to the charger's maximum output current
level. When even more current is drawn, the battery must supply this which results in a

Powersine Combi
17
declining baery voltage. At a certain baery voltage level, the charger jumps back to the
Bulk stage and will finalize a complete charging process again, once the baery load
consumpon has dropped below the charger's maximum output current level.
The fourth stage called “Pulse”, will perform a short refresh charge of approximately 1 hour
each 7 days while the charger operates in the Float stage. This will keep the baery in
opmal condion while prolonging it's lifeme. The baery can remain connected to the
acvated charger connuously, without risk of overcharging.
When the standard selectable charging programs do not sasfy your requirements, or
when different voltage- and current levels are needed, you can edit or create your own
charge programs using SAMLEX Dashboard. Up to 8 different stages can be linked together
and all individual stages can be configured extensively.
5.2 Equalizing a flooded baery
If you are using a flooded lead acid baery, an occasional equalizaon charge cycle may
be recommended by the manufacturer. This might also be true when the flooded baery
has been very deeply discharged or oen charged inadequately. During equalizaon, the
baery will be charged up to 15.5V (or 31V for 24V models) at a reduced output current
level. Before starng an equalizaon charge cycle, the following cauon statements must
be read carefully :
When the baery temperature sensor is installed, the charger automacally compensates
the charge voltages against baery temperature (except when set to Lithium). This means
that the charge voltages are slightly increased at lower temperatures and decreased at
higher temperatures (-30mV/°C at 12V chargers and -60mV/°C at 24V chargers). This way,
overcharging is prevented which prolongs your baery’s lifeme.
!
CAUTION
Equalizaon should only be performed on a flooded (wet) lead acid baery. Therefore the
Powersine Combi only allows equalizaon when the baery type DIP switches are set to
Flooded. Other baery types like GEL, AGM or Lithium will be damaged by this process.
Always follow the baery manufacturer's instrucons when equalizing flooded baeries.
During equalizaon, the baery generates explosive gasses. Follow all the baery safety
precauons enclosed with your Powersine Combi. Venlate the area around the baery
sufficiently and ensure that there are no sources of flames or sparks in the vicinity.
Disconnect all loads connected to the baery during equalizaon. The voltage applied to
the baery during this process may be above safe levels for some loads.
The Powersine Combi cannot automacally determine when to stop the equalizaon of a
baery. The user must monitor the baery's specific gravity throughout this process to
determine the end of the equalizaon cycle. The internal 2 hours me-out mer of your
charger is only intended as a safety feature, but may not be sufficiently short to prevent

battery damage. Therefore, equalizing a battery is always a process that must continuously
be supervised by the user.
Since equalization is only allowed for flooded (wet-) lead acid batteries, the Powersine
Combi will only allow this function to be available when the “Flooded” charging program
is selected (see chapter 3.3). Besides this, the charger also needs to have a full charge cycle
completed and must operate in the Float stage. When these two conditions are met, the
equalization charge mode can be activated by pressing the recessed pushbutton on the
bottom side of the unit (see images below) for 3 seconds, until all charge status indicators
start flashing.
Models : PSC1600-1800 :
Models : PSC2000-3500 :
The Powersine Combi will allow a maximum equalization time of 2 hours before it
automatically jumps back to the Float stage. If the specific gravity of each cell does not
match the battery manufacturer's specifications yet, you can initiate a new 2 hours
equalization cycle by pressing the pushbutton for 3 seconds again. Always keep on checking
the specific gravity of each cell repeatedly during the equalization process. When these
values are correct, you can manually exit the equalization process by pressing the recessed
pushbutton once. The Powersine Combi will then return to the Float stage.

6. TROUBLESHOOTING GUIDELINE
Please see the table below if you experience any problems with the Powersine Combi and/or
the installation.
Problem
Possible cause
Remedy
Powersine Combi is not
working at all.
Main switch in Off (0)
position.
Push the power switch in the
‘I’ or ‘II’ position.
Remote switch or Universal
Remote Control have
deactivated the Powersine
Combi.
Activate the Powersine
Combi remotely or check DIP
switch 8 or 10 for correct
setting.
Poor contact between the
Powersine Combi battery
wires and the battery
terminals.
Clean battery terminals or
Powersine Combi wire
contacts. Tighten battery
terminal screws.
Blown DC fuse.
Check battery fuse or
internal Powersine Combi
fuse (PSC1600-1800 only).
Very poor battery condition.
Replace battery.
The charger mode is not
working (AC transfer switch
does not activate either).
The AC input voltage or
frequency are out of range or
too unstable.
Make sure that the AC input
voltage is between 185V -
270V and the frequency
between 45Hz –65Hz
(assuming standard settings)
Charger mode and/or the AC
transfer switch are disabled
during setup using
Dashboard.
Enable Charger mode and
the AC transfer switch using
Dashboard.
The battery is not being
charged up to it’s maximum
capacity.
Incorrect absorption charge
voltage setting.
Check DIP switch 5 and 6 for
correct settings. Or adjust
the absorption voltage using
SAMLEX Dashboard.
Incorrect charge current
setting.
Adjust the charge current
using the Universal Remote
Control or SAMLEX
Dashboard. Typically, the
charge current should be set
to 10%-20% of the total
battery capacity
Too much voltage loss in
battery cables and/or
connections.
Make sure that the battery
cables have a large enough
diameter. Check if all DC
connections are solidly
made.

Additional battery loads are
consuming too much current
during charging.
Turn-off or disconnect all
battery loads.
Charge current is too low.
High ambient temperature.
Try to lower the ambient
temperature around the
Powersine Combi.
Charger is operating in the
absorption charging stage.
Do nothing. The battery is
almost fully charged and
consumes less current by
itself.
Mode indicator LEDs
‘inverter on’, ‘charger on’
and ‘AC in’ are blinking red
once per second (battery
error).
Battery voltage is too low (<
8V@12V or <16V@24V).
Battery is damaged, replace
it. Or battery has been
discharged too extremely, let
it slowly recover to above
8.5V so that the transfer
switch and charger can
startup to recharge the
battery.
Battery voltage is too high
(>16.5V or >33V@24V).
Check the DC system for an
external source that pushes
the battery voltage too high.
Too high ripple voltage on DC
input. (manual restart
needed)
Check battery wire
connections. Decrease
battery cable length.
Increase battery and/or
cable size. Make sure that no
other equipment on the
same battery is generating a
high ripple voltage.
Only mode indicator LED
‘inverter on’ blinks red once
per second.
Battery voltage is too low
(<10V@12V or <20V@24V).
Apply mains voltage to the
AC input and start charging
the battery.
When another turn off
voltage is desired in ‘Battery
protect On’ mode, please use
